Paper-Holders for Type-Writers, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to the alining scale of typewriting machines, and has for its object to provide a combined alining scale, printing point indicator and cardholding device, of simple and practical construction, indicating at all positions of the platen the exact printing point upon the paper", permitting the operator to write to the extreme bottom or top edge if desired, yet which will be of few parts, simple and easy to manufacture and assemble.

In the accompanying drawings, wherein are shown one of many possible embodiments of my invention, Figure 1 is a plan view of a part of the typewriting machine sufficient to illustrate one embodiment of the present invention; 1F ig. 2 is a side elevation of the same; and Fig. 3 is a detail front view of the alining scale and its mountings.

Similar reference characters refer to similar parts throughout the drawings.

While the present invention is illustrated and described with reference to that form of machine known as the Noiseless typewriting machine, it is to be understood that this invention may be applied to other forms of typewriting machines.

Referring now to the drawings in detail, 1 represents a shiftable platen carriage on which is mounted a revoluble platen roller 2 and a relatively stationary flat platen 3 over which the paper passes and with which the type carriers (not shown) co-act. The carriage l reciprocates on a shift rail 4 movable in opposite directions from a normal intermediate position for the purpose of rintin u er or lower case characters.

Centrally disposed and rigidly connected with this shift rail 4: is a projecting part or support 5 which by means of trunnions 6 supports a bearing plate for the upper end of a telescopically constructed escapement shaft 7. This shaft 7 .is provided with a plnlon 8 meshing with a. rack 9 mounted on the lower part of the carriage 1. On the support 5 are forwardly projecting ears or lugs 10 having vertical slots 10 therein through which pass trunnions 11 supporting a rock shaft 12 on which are loosely mounted two connected arms 13 provided at their upper parts with laterally extending wings or scale portions let having an intermediate cut-away portion 15 indicating the printing oint. The slots 10 permit a vertical ad- ]ustment of the scale and the cut-away portion 15 allows the type carriers to move freely forward into engagement with the paper over the platen 3. A spring 16 is spirally Wound around the shaft 12 and rigidly connected at one end to a relatively fixed part and at its other end to one arm 13; it normally urges the arms and scale carriedthereby into engagement with the flat platen 3, as clearly shown in Fig. 2.

The spring 16 has sufficient tension to hold the arms 13 and scale portions carried thereby in close contact with the platen, or to hold the paper or card closely adjacent the printing point. As the flat platen 3 is stationary with relation to the carriage at all times, and with the scale except when the carriage is being spaced, the scale may press it with considerable force, so that the paper is held firmly in place, allowing the operator to write at the very bottom or top of the sheet. paper clip or card holding device, and being shiftable with the platen will allow the operator to print upper and lower case type without fear of the paper slipping from between the card holder and the platen.

In this manner the scale acts as a l Should it be attempted to use a scale of this It is thus seen that by loosening these locknuts the threaded pins or trunnions may be moved in opposite directions laterally to adjust the scale relatively to the printing I point, and they .may also be moved vertically in the slots 10 to adjust the same vertically, after which when the scale is in adjusted position the lock-nuts 17 and 18 may be tightened to hold the scale firmly in adj ustedposition.

Mounted in the upper part of the supporting block 5 are ribbon guides 19 which are bent outwardly and upwardly, carrying at the upper part thereof suitable holding means 20 for the ribbon, whereby the same is held in position to be engaged by the type carriers and moved therewith to the impression point.

The manner of use andoperation of this device is as follows: The paper is inserted beneath the platen roller 2 and over the fiat platen 3, forcing the holder or indicator 1% away against the yielding action of the springs 16. The upper edge enables the operator to determine the line position while the intermediate cut-away portion 15 between the laterally extending arms 14 will denote the exact point of impression of the next character to be printed. When the carriage is shifted by means (not shown) applied to the ends of the'rail 4 in any suit able manner, the support 5 is carried thereby with the upper part of the telescopically constructed escapement shaft 7 so that the scale and ribbon guides all move t gether to indicate to the operator the point of impression.

As the wings 14 bear with considerable pressure against the platen, it is to be noted that a plurality of sheets of paper may be fed around the roller and held against the platen with suificient force to enable printing to be effected, even at the very bottom of the sheet, while if a card is inserted it will be held against the printing point in all positions and may conform to the curve of the platen roller with the aid of the usual feed rollers and clips, not herein shown.

It is thus seen that this invention provides for a simple and practical device adapted to accomplish, among others, the

objects set forth, in which the alining scale.

is always held in contact with the paper about the platen to indicate the alinement and also the exact printing point at which the next character is to be printed, whether p, the carriage is shifted for upper or lower case, characters. The scale being held normally in yielding contact with the platen, any reasonable number of sheets of paper maybe inserted, thereby increasing its ethciency and allowing the operator to write at any portion of the sheets. Being yieldingly held in this manner, the scale acts as a satisfactory clip or card holder allowing the op erator to write" on paper of any quality or.

size.

messes As many changes could be made in the above construction and many apparently widely different embodiments of this inven tion could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is 2* 1. In a typewriting machine, in combination, ashiftable platen carriage, a flat platen secured between the end plates thereof, a shift rail vertically disposed beneath the central longitudinal dimension of the carriage and along which the carriage is adapted to travel, said shift rail having a for wardly projecting part, and a vertically disposed alining scale mounted on the forward portion of said part adapted normally to bear against and indicate the printing point upon said flat platen.

In a typewriting machine, in combination, a reciprocating carriage, a flat platen carried thereby, a shift rail on which said carriage is adapted to travel, a projection on .said rail, 'and vertically adjustable indicating means pivotally mounted on said projection adapted to indicate the printing point on said fiat platen.

4. In a typewriting machine, in combination, a reciprocating carriage, a flat platen carried thereby, a single shift rail beneath and on which said carriage is adapted to travel, a projection on said rail, and paper holding means pivotally mounted on said projection adapted to engage said platen.
